Bipedal motion?

Question

If I took a baby born in 2008 and transported it BACK to the prehistoric age it would never learn to walk. No one is walking so how could it learn. Most things we do today the baby would never learn to do. Most things are a learned behavior in the human species. So my question is this?

If I transported a prehistoric baby FORWARD to the year 2008 would it learn to walk just like any other child would learn?? I'm talking straight out of the womb.

The reason I ask is that I'm having an intense debate with a fellow student about evolution. I contend we evolve through intelligence. He contends we evolve through genetics. I understand his point but my point is intelligence forces the body to change. It forces genetic evolution. Where the mind goes the body will follow proposal I've been kicking around.

So basically, my contention is we are the same now as we were 50 thousand years ago. The only difference is that we have become more intelligent.

<<So basically, my contention is we are the same now as we were 50 thousand years ago. The only difference is that we have become more intelligent.>>

That differs from the view of most scientists in only one regard.  We haven't become more intelligent over the last fifty thousand years.  Brain size of /H. sapiens/ was about as large then as now.  Rather, we've got a better supply of information by the availability of the written record, and we have a much stronger degree of specialisation supported by a more complex society with a greater number members.
